    I would look for a vacuum leak or maybe even a boost leak. If you replace any vacuum lines, be sure to use the stock inner diameter and T fitting etc. (also don't lose the restrictor pill).

    Although, with the stock tuning that may be normal (it does some weird stuff at part throttle). Does it boost normally when you floor it?
